Re: [equinox-dev] install workspace plug-ins on Equinox

java.lang.ClassNotFoundException: hello.Activator
please check the classpath option in your MANIFEST.MF.

 
2007/3/30, ChangWoo Jung <jungcw@xxxxxxxxxx>:

Hello folks,

I just want to install the workspace plug-in into equinox using self-hosting bundle project not using the jar packaging.
I guess it was supported by enabling the dev mode in the past (-dev)

But it gives me below error. (I used simple HelloWorld plug-in.)
It seems that if dev.properteis (which usually auto-generated when clicking the workspace plugin before launching) is missing then can't find the classes. (like "Hello=bin")

I guess this problem also can be occurred inside IDE.
If I don't check the workspace plug-in and start the equinox and later if I attempt to install workspace plug-in which was not chosen before and try the command like "install reference:file:[project_name]" then it gives me same error.

Do I miss something?
